STAPL FORMINGAND DISCHRGIG MECHANISM.

Specification of Letters Patent. Application iiled July 5. 1907. Serial No. 382.247-

Patented Feb. 25, 1908.

To all whom it may' concern:

Beit known that I, VER-NON Hoxin, a citi'- zen of the Uni-ted States, and a resident of Adrian, in the county of Lenawee and State offMichi an, have invented a certain new and useful `taple Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichy it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures and letters of reference marked thereon, which forni a part of this specification.

My invention relates to wire-working Inachines, and particularly to wire-sta le forming mechanism for' use in wire-fa ric machines, which mechanism is designed to form a staple from a section of wire fed thereto, discharge it therefrom and finally clamp it about the intersecting portions of a fabric, the wires of which are intermittently fed by suitable mechanism in a plane intersecting the plane of discharge of said staples.

The object of my invention is to simplify and improve upon the construction and operation of apparatus of this class, whereby to enhance the practicability and commercial value thereof.

The operation, construction and arrangey ment of the parts of the invention are fully described in the following s ecification and illustrated in the accompanying drawings, iny

which,

Figure 1 is a side elevation of a portion of a loom equipped with my invention and illustrating an associated operating mechanism. Fig. 2 is a side elevation of the mechanism comprising my invention with one side of the inclosing casing removed. Fig. 3 is a section of the samel on the line c a in Fig. 2. Fig. 4 is a transverse section on the line b b in Fig. 5. Fig. 5 is a view similar to Fig. 2 with the plunger nearing the completion of its forward movement. Fi 6 is an enlarged section on `the line b b in Fig. 5 with a staple lying in advance of the dischar 'ng plunger. Fig. 7 is a perspective view of t e pressure-block, which cooperates with the staple during the forming o eration. Figs. Sand 9 are interior views o ay sli htly modified form of the invention with t ey lunger shown in different positions, and igs. 10 and 11 are transverse sections onv the line c c in Fig. 8 at diierent points'of movement of the plunger.

Forming and Dischargingthus causing tongue 8 by the block 1 vfreely from their forming to Referring tov the drawings, land' 2 designate the-longitudinally separable parts of theA holder or member within which the forming and. discharging means of my invention are mounted. The parts 1 and 2 havertheir in^- ner faces provided withlongitud-inal recesses or slide-ways 3 and 4, respectively, in which theplunger 5 is reciprocally mounted, thel latter of said recesses being of greater length thanthe other and broadened to ermit themovement therein of the stap e-forming plate 6, which is attached to the forward end of the plunger. This plate is provided at its forward end with a recess 7, which, on the forward movement of the plunger, is intended to cooperate with a fixed aliningtongue or rib 8 to form a severed section of the wire 9 into a U-shaped'staple 9', as shown. Mount ed in an opening 10 in the part 2 and strade dling the tongue or rib 8 is a U-shaped res# sure-block 11, which is yieldingly held y a spring 12 with its leg terminals normally disposed iii the ath of movement of the plate 6. The legs of t e block closely hug the sides of the tongue8, and are intended to operate to eject a staple laterally from the tongue after the staple has beeny formed and the plate 6 has receded from over the block. The plate 6 on its forward movement has contact with the inclined surfaces 11 of the' block and causes the block to move outwardly against the tension of the spring 1.2 out of the path of movement of the late.

The staple after eing formed is discharged from the apparatus and driven around the intersectingwires of a fabric by the discharging tongue 13. This tongue rigidly projects from the forward end of the plunger 5 and lies in a plane which, preferably intersects at right angles that of the plate 6, as shown, the staples to describe a quarter turn as they are ejected from the rib or 1 and to fall flat upon the tongue 13 in position to dro in advance thereof as it recedes from un er the same. The tongue 13 operates in the bottom of a chamber 14 and through an alining discharge passage in the forward endl l of the part 1, asshown, the chamber 14 bein of suitable size to permit the sta les to faltheir discharging the upper face of position, as shown.

. 16 designates a guide-iinger which is sh" wn as being carried by the part 1 in contact with the face ofthe rib or tongue 8 and as curving Youtwardly anddownwardly therefrom, as

shownin Figs. 3, 4 and 6. The purpose of this fingeris to guide the movement of the staples as they drop from one position to the other so that instead of permitting the same to fall straight and rest upon one leg on the discharging tongue 13 they are caused to describe aq'uarter turn and fall fiat upon said tongue, as best shown in Fig. 6.

The Wire 9 is intermittently fed to the forming parts through an apertured die 17 mounted in the parts 1 and 2 and through almmg grooves 1-8 provided in the inner `faces of the rib or tongue 8 and the legs of the `with the former is mounted a semi-gear 25 which meshes with asemi-pjnion 26 on the shaft 27 and through it communicates rotation to the gear 28, which drives the small gear 29 through the medium of the idler-gear 30.- The gear 29 is carried by one of a pair of feed-rolls 31 between which the wire 9 passes and is frictionally gripped to cause it to be fed to the forming apparatus whensaid rolls are rotated, thus causing a properly timed intermittenty movement to be communicated to said wire from a continuous rotation of the gear 22. Mounted on the shaft with the gear 23 is an eccentric 32 carrying an eccentricrod 33, which connects with knuckles 34 and through them imparts a reciprocatory movement to the plunger 5 of the associated staple-forming apparatus.

The modification shown in Figs. 8, 9, l() and 11 consists in the provision of means for use in lieu of the guide-finger 16 for causing a positive turning of the staples from their forming to their discharging positions. The

change consists in extending the chamber 1 4 through to the top of the part 1, as shown at a, and mounting a block l) therein, which block is yielding held in lowered position by a spring c. The inner end of this block is y transversely rounded, as shown at d, toadapt -it whenpressing inwardly against one leg of n a staple standing up in the position4 shown in Fig. 10 to cause positive movement of the staple toreclining position, as show-n` in Fig. 11. vDuring the forming of a staple the block b is raised above the same by the coaction therewith of the finger e, 'which is fixed to the p, side of the plunger 5 and travels in a runway f in the part 1, asshown.

4This finger has its nose beveled,"as at. g, to adapt` it to enter a e5' transverse recess, hiin the side of the block bl and force the block to elevated -position dur-l ing the forming of a staple. `It is thus a parent .that as the block 1] forceslthe staplle from the rib 8 on the recession of the late 6 therefrom, the straightening-block b wi l be re'- leased from the finger e and caused by the spring c Atomove inwardly and effect a straightening of the staple in position tobe engaged by the discharging-tongue 13l on its forward movement.y

The operation of the invention is as follows :-During each rearward movement ofthe plunger 5 and after the plate 6 has receded ast the die 17 a section of Wire 9 is fed to the orming parts by a properly timed movement of the feeding mechanisnl.l On ythe forward movement of the plunger the plate 6 bothsevers the wire' and forms the severed section into U-sha e around the rib or tongue 8, the pressure-blbck 11 being forced outwardly by the contact of the plate therewith. The plunger and plate then recede to permit the pressure-block 11 to force the staple from the rib 8 and cause it to fall to the bottom of the chamber 14 upon the dischargingtongue 13, which is receding with the lunger, the falling movement of the stap e being guided either by the guide-finger 16 or the action of the block b so that the staple will lay fiat upon the discharging-tongue. The plunger recedes sufficiently for the staple to drop in advance of the tongue13, and-on the subsequent forward movement of the plunger the staple is discharged from the apparatus and clamped around two of the wires at their points of intersection or other alining object. staple is being forme charged.

I wish it understood that I do not desire to be limited to the exact details of construction shown and described, as obvious modifications will occur to a person skilled in the art; and also that while I vhaveffparticularly described my invention as being for use in connection with a wire fabric machine the same may be used separately or in connection with other machines for similar or analogous pur ose's, without departing from the spirit of t e claims. i
